Description

  • This invention relates to a self-engaging composite separable fastener product of the hook and loop-type. The invention also relates to a method of producing the inventive product.
  • Hook and loop fastener strips are well known and are used to join two parts detachably to each other. These fastener strips consist of mating fastener tapes having hooks and loops set respectively on either tape, which on being pressed together will interlock and so form a connection. Such fastener strips are employed in numerous applications including wearing apparel, for example outer apparel, and are also found on footwear and leather goods such as bags or the like.
  • Such hook and loop-type fasteners are described in US Patents Nos. 2,717,437 and 3,009,235 which are marketed under the Registered Trade Mark VELCRO brand hook and loop fasteners by Velcro USA inc., Manchester, New Hamp- shire 03108, USA, have gained wide acceptance because of the properties of the mating hooks and loops which permit their attachment by merely placing a surface defined by the hooks into face-to- face relationship with a surface defined by the loops so that a large number of hooks engage a large number of loops which resist separation parallel to the interfacial plane of engagement but are readily separable by peeling forces applied substantially normal to this interfacial plane. The loop component of these fasteners is generally formed of a sheet of woven fabric having raised threads of multifilament synthetic material, such as nylon, which are napped or unnapped, to provide a pile surface defined by a plurality of loops, and which may be thermally treated to become semi-rigid. The hook part of these fasteners is generally formed of a separate sheet of woven fabric having raised monofilament loops which are subsequently cut to form hooks.
  • While these fasteners provide excellent holding properties where repeated engagements and disengagements are required, often it is desirable to provide a continuous fastener member having one section containing upstanding loops and a second section containing upstanding hooks so as to enable portions of the fastener to be folded upon themselves to provide the necessary fastening, as by placing the fastener in tension when utilised as a fastener for footwear.
  • In US Patent No. 4,426,363 a composite length of pile fabric sheet material is disclosed whereby two sections of such mating fastener materials are joined together. Thus the hook section can be matched with the loop section (i.e. hook and loop relative densities and heights) to provide effective fastening and separation of the sections. While this invention has been successful over the years, the fastener nevertheless requires a separate step to join the separate sections, thus not only adding to the cost of manufacture, but introducing an element of potential weakness in the strap. Moreover, since the sections are often joined by ultrasonic welding or stitching techniques the fastener sections are overlapped with each other thus creating an area of increased thickness and resistance to folding. This sometimes presents a particular disadvantage such as in footwear applications where added thickness to the fastener can cause added discomfort to the wearer.
  • Subsequent to the development of the fastener of US Patent No. 4,426,363 (Girard) attempts were made to weave a composite fastener on a single loom whereby adjacent hook and loop tape sections could be produced having a common base member. However, these fasteners had insufficient desirable holding power because the loop density of the loop section thus produced did not match the hook density of the hook section. We have invented a composite self-engaging fastener which avoids these aforementioned disadvantages.
  • The document EP-A-0 106 771 describes a tennis court net suspended from its tensioning wire by a releasable band folded over the wire and secured to the net by a hook-and-loop type fastener, with the hooks and loops engaging through the holes in the net. The band may be in woven form, and as described it has two edge regions, one at each side extending in the warp direction and separated by a central region. One edge region has its actual warp threads of monofilament yarn, which are formed during the weaving process into hook-forming loops. The other edge region has its actual warp threads of multifilament yarn, and these threads are likewise formed into loops, with each loop of one edge region having a single corresponding loop in the other region, i.e. there are the same number of loops in the two regions. The hook forming loops are then formed into hooks by application of heat to cause partial melting of the monofilament fibres. There are no hooks or loops in the central region separating the edge regions, and it is this central region that is folded over the tensioning wire. The hooks then co-operate with the loops of the other edge region to secure the two edge regions together face to face, being releasable by peeling the edge regions apart. Since all the warp threads are parallel to each other, the loops in each warp thread extend parallel to those in the other warp threads.
  • According to the present invention, a self-engaging separable fastener having at least two mating fastener sections, a woven base common to said sections, and mutually engageable fastening elements, upstanding from the base in generally parallel rows and comprising fastening loops in a first said section and hooks in a second said section, the hooks being cut from hook forming loops, the fastening loops and hook-forming loops being defined respectively in multifilament yarns and monofilament yarns extending parallel to each other in the warp direction of the base, with the loop direction of the fastening loops repeated every predetermined number of picks of the base and that of the hook-forming loops and therefore of the hooks, repeated every predetermined number of picks of the base, whereby said sections are engageable face to face by folding the base and pressing the sections together, and separable by peeling them apart, is characterised in that, in the warp direction, the said number of picks between successive hooks of common loop direction is greater than that between successive fastening loops of common loop direction.
  • Preferably, the said multifilament and monofilament yams are interwoven with the base, being additional to the warp yarns of the base. The first and second fastener sections are preferably contiguous.
  • The base and the fastening elements of the self-engaging separable fastener of the present invention are preferably formed from nylon yarns. Alternatively the base and/or the upstanding elements may be formed of polyester or polypropylene yarns or various combinations thereof.
  • The self-engaging separable fastener of the invention preferably comprises a backing substrate of at least one of vinyl, leather and canvas attached to the side of said base opposite the side thereof from which the fastening elements extend.
  • In preferred embodiments of the invention, in each said row of hooks, the interval in the warp direction between successive hooks of common loop direction and construction is about double the interval in the warp direction between successive fastening loops of common loop direction and construction.
  • According to a further aspect of the present invention, in a method of producing a self-engaging separable fastener, which comprises: feeding to a weaving loom, base yarns, multifilament loop yams and monofilament hook yarns; weaving a base across the width of the loom while simultaneously interweaving into a first section, a plurality of multifilament loops, and into a second section, a plurality of monofilament loops, the multifilament loop direction and construction being repeated every predetermined number of picks, and the monofilament loop direction and construction being repeated every predetermined number of picks, said latter number of picks is greater than the number of picks for which the direction and construction of said multifilament loops are repeated, and the said sections are adjacent to each other.
  • Preferably, the method also comprises subjecting the fastener to a scouring solution to scour the yams. Thereafter the fastener is advantageously subjected to a napping operation.
  • The method also preferably comprises subjecting the fastener to heat sufficient to heat set the multifilament and monofilament loops and the common base, and thereafter applying an adhesive type coating to the rear surface of the base. Either water based or solvent based adhesive may be applied. In addition the method further comprises cutting the monofilament loops to form hooks, and possibly dyeing the fastener prior to applying said adhesive coating to the rear surface of the base.
  • A substrate material may be attached to the rear surface of the base of the fastener. Further, the fastener is preferably cut into strap sections along cut lines oriented at an acute angle with respect to the direction of the warp yarns.
  • In one preferred form the method of producing the self-engaging separable fastener of the invention comprises: feeding to a weaving loom, base yams, multifilament loop yarns and monofilament hook yams; weaving a base member across the width of the loom while simultaneously interweaving into a first section, a plurality of multifilament loops and into a second section, a plurality of monofilament loops, the multifilament loop direction and construction being repeated at least every four picks, and the monofilament loop direction and construction being repeated at least every eight picks, whereby the number of interwoven monofilament loops per unit length along the warp direction is approximately half the number of interwoven multifilament loops per unit length along the warp direction; and cutting the monofilament loops to form hooks.

  • In the description which follows "hook-like elements" are sometimes referred to as "hooks", and "loop-like elements" are sometimes referred to as "loops". Since the hooks of the hook section are cut from monofilament loops, for convenience, the "hooks", and the "hook section" are sometimes referred to as "monofilament loops" or "monofilament loop section", respectively. The subsequent conversion of the monofilament loops to monofilament fastening hooks is thus contemplated and described. Moreover, since the multifilament fastening loops of the loop section are ultimately napped to form a greater number of fine filament loops than the number of multifilament loops which are first interwoven into the base member, for convenience the loops of the loop section are sometimes referred to as "multifilament loops". Thus a single "multifilament loop" will provide, after napping, a plurality of fine filament loops.
  • Referring now initially to Fig. 1, there is illustrated the self-engaging separable fastener 10 of the invention having a first fastener section, or loop section, 14 defined by a woven base 16 having a plurality of upstanding multifilament loop-like elements 18 and an adjacent and contiguous second fastener section or hook section, 12, defined by a continuation of (i.e. part of) the base 16 and having a plurality of upstanding hook-like elements 20'. The base member 16 is common to both sections 12 and 14 and the loop-like elements are formed by interweaving a plurality of multifilament yarns into the base member 16 so as to define the upstanding loops 18, while the hook-like elements are formed by simultaneously interweaving a plurality of monofilament yarns into the base member 16 so as to define hook-forming monofilament loops 20 upstanding from the base member 16. Thus the multifilament loops and the monofilament loops, which are preferably additional to the warp yarns of the base itself, and which (as can be seen from Fig. 5) extend parallel to each other in the warp direction, are woven into the base member 16 while it is being formed. Thereafter the surface is napped to separate the individual multifilaments of fine yarns which form the multifilament loops so as to provide a thick, plush surface. Also, the monofilament loop elements 20 are cut to form upstanding monofilament hooks 20' as shown in Fig. 2 so as to be suitable for engagement and disengagement with the plush surface of fine filament loops.
  • Referring once again to Fig. 2 there is illustrated the self-engaging separable fastener 10 of Fig. 1 taken along lines 2-2 of Fig. 1. In this drawing there is illustrated the fastener 10 having woven base member 16 and monofilament hook elements 20' which have been cut from monofilament loops 20 (Fig. 7).
  • The self-engaging separable fastener is preferably constructed of any combination of synthetic yams such as nylon, polyester, polypropylene, or the like; however depending upon the end use and particular needs, any combinations of such yarns - or even alternative suitable equivalent yarns - may be included in the fastener. For example, for certain properties which may be desired, or for environmental reasons, the base member may be constructed of polyester, while the hooks and loops may be constructed of nylon, polypropylene or the like, or vice versa.
  • Referring now to Fig. 3, there is illustrated a typical application of the self-engaging fastener of the invention, namely as a fastener for an article of footwear such as shoe 24. In this application a strip of the woven self-engaging fastener 10 has laminated to the rear surface of the base member 16, a suitable layer 28 of leather, vinyl or the like. The material selected will normally depend upon the material of the main product 24 (in this case, the article of footwear). The combination strap 30 is adapted to be attached to the shoe 24 by buckles 32 and 34. Thus when the strap is attached to buckle 32 and looped through buckle 34 it may be pulled tightly so as to fasten the shoe and thereafter the hook section may be pressed against loop section 14 to maintain the shoe in tightly fastened condition as illustrated in Fig. 4. The potential applications of the present invention are legion and will be readily apparent to one skilled in the art. For example, such industries as the garment industry, the luggage industry, or the automobile industry will find this fastener to be readily applicable to their needs due to its composite structure which uniquely provides readily available fastening capability of both sections without the need for stitching, ultrasonic attachment, glueing, or the like.
  • Referring now to Fig. 5 there is illustrated a preferred construction of the separable fastener member 10. In the construction illustrated in Fig. 5, the warp yarns 36 of the base 16 are shown extending approximately vertically as the fabric emerges from the loom, and its weft yarns 38 are shown generally horizontally as they emerge from the loom. We have found that when the same construction is used for both the hook section and the loop section the density of hooks is too great to permit proper penetration of the hooks into, and in engagement with, the loops. However, by uniquely simultaneously constructing the loop section to have greater density than the hook section - over a common base member - we have discovered that the proper penetration of the hooks into the loops will take place and will provide proper securing of the two sections of the fastener. This is particularly accomplished by the construction as shown in the drawings, and will be described hereinbelow.
  • Referring now to Fig. 6 in conjunction with Figs. 7 and 8, the loop section 14 and the hook section 12 of fastener 10 are illustrated. The fastener is woven on a suitable weaving loom which is adapted to interweave multifilament loops 18 and monofilament loops 20 (eventually to be cut to form hooks 20'). The multifilament loops are preferably constructed so as to repeat their direction and construction every four picks (i.e. every four wefts) and the monofilament loops 20 are preferably constructed to repeat their direction and construction every eight picks (i.e. every eight wefts). Thus the result of such weaving construction is that the hook section is less dense than the loop section; or expressed otherwise, the multifilament loops per unit length along the warp direction is approximately one-half the number of interwoven monofilament loops per unit length along the warp. Broadly stated, however, our invention contemplates a construction where the monofilament loops repeat their direction and construction every predetermined number of picks, whereby the number of picks for such occurrence for the monofilament loops is greater than the number of picks for which the multifilament loops repeat their direction and construction. Within such definition, any combination of respective repeat patterns may be developed, provided that the density of the multifilament loops is greater than the density of the monofilament hooks, and the proper relative lengths of the loops and the hooks is selected.
  • Referring now to Fig. 7 there is illustrated the weave pattern of the hook section 12 as viewed along lines 7-7 of Fig. 6. In Fig. 8 there is illustrated the weave pattern of the multifilament loop section 14 as viewed along lines 8-9 of Fig. 6. In the preferred construction shown - i.e. multifilament loops repeat their direction and construction every four picks and monofilament hooks repeat their direction and construction every eight picks - the monofilament hooks tend to become interwoven by a "W" weave, whereas the multifilament loops are more tightly woven into the base member. In order to more properly secure all of the members - multifilament loops as well as monofilament hooks - in accordance with the method of the invention an adhesive coating is applied to the rear surface of the base member after the fabric is heat set to stabilise the construction as will be described hereinbelow. Such adhesive may be a suitable water based or solvent based adhesive, depending upon the intended end use.
  • Referring to Fig. 10 the method of producing a self-engaging fastener according to the invention is illustrated in schematic block diagram form. The loom has introduced thereto, base yams, multifilament yarns (for loops) and monofilament yarns (for hooks). The fastener fabric is formed on the loom with base 16 woven from the base yarns, which base is common to loop section 18 and hook section 20. The loom is suitably equipped for such simultaneous weaving operation by incorporating the appropriate harnesses and camming devices.
  • After weaving, the fabric is subjected to a scouring process during which the weaving oils and other contaminants are removed. Thereafter the fabric is subjected to appropriate heating at a temperature sufficient to heat set both the upstanding multifilaments and monofilaments and the base member to stabilise the upstanding loops and the base member and thereby improve the tightly woven grip which the woven base member retains on the loops. After heatsetting, dyeing of the fastener fabric is optional. The fabric is then subjected to a napping procedure in which the upstanding loops are subjected to the action of a rotating wire brush which separate the various filaments of the multifilament loops to provide a plush, thick surface of fine filament loops. It has been found, however, that notwithstanding the fact that the monofilament loops (i.e. to be cut to form hooks) and the multifilament loops are on the same surface, the napping brush does not adversely affect the monofilament loops. Accordingly, for convenience both surfaces may be subjected to the same napping operation to which fastener fabrics having multifilament loops alone are subjected.
  • After napping, the rear surface of the base member 16 is coated with an adhesive material to further stabilise the base member as well as to increase the relatively tight hold which the base weave has on the upstanding members. Thereafter, the fabric is subjected to a hook cutting operation in which the monofilament loops 20 are cut as shown in Fig. 2 to form monofilament hooks 20'. As noted previously, the finished fastener tape may be attached directly to an end use product or it may be provided with an additional backing material such as a leather, vinyl, canvas, etc. backing member which would be laminated or otherwise attached to the rear surface of the base member for use in securing end use articles such as footwear as shown in the manner illustrated in Fig. 3. As noted, other potential applications are legion.
  • Referring now to Fig. 9 there is illustrated a preferred technique for cutting out fastener fabric into fastener straps of lesser width and of efficient construction which maximises the use of the hooks and the loops. For example, in footwear applications as shown in Fig. 3, it is only necessary to include a hook section of shorter length than the loop section. Thus, as shown in Fig. 9, the width of the loop section as seen on the loom is greater than the width of the hook section. Thereafter by cutting the fastener member - as shown - into relatively narrow strips oriented at an acute angle "A" with respect to the side edges, the resulting fastener straps 40 will have a loop section 42 greater in length than the hook section 44. This arrangement is often desirable, as it facilitates sufficient securement and adjustability by permitting the user to readily tension, and press and peel the hook section at predetermined locations along the loop surface, depending upon the degree of fastening tension desired in a given application.
